Zero Trust Architecture: NIST Publishes SP 800-207
By CHIPS Magazine - August 12, 2020
The National Institute of Standards and Technology announces the final publication of Special Publication (SP) 800-207, Zero Trust Architecture, which discusses the core logical components that make up a zero trust architecture (ZTA).

"Zero trust (ZT) is the term for an evolving set of cybersecurity paradigms that move defenses from static, network-based perimeters to focus on users, assets, and resources. A zero trust architecture (ZTA) uses zero trust principles to plan industrial and enterprise infrastructure and workflows. Zero trust assumes there is no implicit trust granted to assets or user accounts based solely on their physical or network location (i.e., local area networks versus the internet) or based on asset ownership (enterprise or personally owned)," NIST explained in a release.

Authentication and authorization for a user are discrete functions performed before a session to an enterprise resource can be established. Zero trust is a response to enterprise network trends that include remote users, bring-your-own-device (BYOD), and cloud-based assets that are not located within an enterprise-owned network boundary. Zero trust focuses on protecting resources, such as assets, services, workflows, network accounts, etc., not network segments, as the network location is no longer seen as the prime component in the security posture of the resource, NIST reported.

SP 800-207 contains an abstract definition of zero trust architecture (ZTA) and gives general deployment models and use cases where zero trust could improve an enterprise’s overall information technology security posture.
